I APPARATUS FOR THE BROJECTION OF MICROSCOPIC IMAGES.

Application Med December 4, 1923, Serial No. 678 ,504-, and in France December 21, 19:22. I l

The present invention has for its object the provisionof an apparatus which permits of rendering visible to several persons the projections obtained from a micro scopic image and of photographing, these projections. 2 I a The apparatus comprisesthe' combination of a microscope provided with suitable reflecting mirrors or prisms :and a source of light together with a supporting casing the walls of which carry projection screens or photographic mounts,."the said casingbeing provided with suitably disposed screens or partitions which divide thesupporting casing into two compartments so that the rays from the luminous source do not interfere with the reflected rays.

The invention further relates to certain particular arrangements which are hereinafter described. 1

The accompanying drawing represents a,

casing intended for the croscop1c images in accor .vention.

(pro ection of miance with the in:

It reference be made to the drawing,. -itf" will be seen that the microscope which may; be of any suitable type is indicated at- '1;

be secured by Letters Patent is the'said microscope sup cited 1) "a base piece 2 which rests on the m y the casing or box 4 which is provided withone or more than one door 5. The front wall 6 of the box is provided'with two open.- ings 7 8. The bottom 3 is extended behind the wall 6 of the box so as to carry a source of light disposed in front of the opening 8. The luminous source employed is preferablyan electric lamp combined with a resistance 1}) which permits of varyin luminous tendency of the projection. am The microscope 1 is rovidedas usual "wit a lower orientable mlrror 11 intended to. il-

luminate the object, the upper part of the apparatus carrymg also an orientable mir ror intended to reflect the luminous rays coming from the object onto the opening 7- which can be provided with a screen '13. In connection with the foregoing it is to be noted that the 'mirrors are positioned in substantial alignment with the openings 7 and 8 so asto ensure of the proper reflection and projection of the light rays. One or more than one screen 14 is disposed in atoms of the" ranged in the lower opening for project rays into the light chamber, a screen mounted in the upper opening, and mirrors the box 4 with the necessary openingsfor the. passage of the microscope and in'such manner as to divide the box into two compartments, aflowe'r compartment which receives the luminous rays from the source of light 9, the. upper compartment being protected against direct lighting by the rays from the luminous source passing through screen 14- so asto avoid the'interference withthe projection.

By reason of this mounting an apparatus is obtained which comprises a microscope,'adjustable mirrors on the upper and lower ends thereof, a source of light and a 1 -:the pro ection. and the microphotography of opaque bodies.

Havingthus full I described the invention what is claim as new and desired to verse partition therein dividing the easing.

into an up er dark chamber and a lower light cham er and provided with an o ning, -a microscope mounted in the llght chamber and projecting through the opening. in the fpartition into the dark chamber, one wall 0 and lower openings, a source of light aradjustably mounted on theupper and lower ends of the microsco e and positioned re-.

spectively inforwar alignment with the upper and lower openings; for projecting lig t rays from the source of light through the microscope and for projecting therays received ,from the microscope upon the screen. i. I
